IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent No. 127,204, dated May 28,1872.

To all whom it may concern:

Be it known that we, GEO. S. WALKER and FRANK F. ADAMS, of Erie, in thecounty of Erie and State of Pennsylvania, have invented a new andImproved Washing-Machine, and we do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawing and to the letters of reference marked thereon.

Our invention consists in providing certain improvements inwashing-machines.

The accompanying drawing represents our invention as follows:

Figure 1 is a side view of one of our machines, with the tubto which itis attached in section. Fig. 2 is an end view of our machine with partof the end-board broken away, so as to show the workings of a portion ofour machine more perfectly. Fig. 3 is a transverse sectional view of therolls H H, the lines a: w in Figs. 1 and 2 being the lines of section.Figs. 4 and 5 are views of detached parts of our invention--viz., theattaching brackets used to attach the machines to the tubs.

Thefollowing is a description of the construction of our invention: Theframe-work of our machine is composed of the bed-piece N, uprights orend pieces D D, and cross-piece E. Within this frame-work are hung theworking parts of our machine. They consist of the large corrugatedrubbing-roller B, which is hung on the shaft I, and operated by thecrank P and the small rollers H H H. The section view, Fig. 3, showsthese most plainly. They are a series of small rollers so placed thatthey shall surround the lower part of the large roller B. These smallrollers all have their journals in the end boards D D. The constructionof these rollers is as follows: They are all constructed with annulargrooves, which are of equal depth and equal width, and are separatedfrom each other by a space equal to the width of the grooves, so thatthe annular rim thus formed on one roller will fit in the annular grooveof its adjacent roller. Thus the system of rollers all match togetherand form an uneven surface below the rubbing-roller B. This constructionof the lower or smaller rollers adds to the cleansing power of themachine; but the chief object of this form of construction is to preventclothes from passing in between the small rollers, which object isthoroughly accomplished. The rubbing-roller B is self-adjustingvertically. This is accomplished by having the shaft I operate in a slotin the end boards D D, and journaled on sliding journalboxes J, whichare guided in their vertical action by the rods L, which pass throughthe cross-piece E. It is evident that this vertical automatic adjustmentmust be regulated by some kind of a yielding pressure. This is providedby the spring K, which is coiled about the rod L, and operates againstthe sliding journal-box J, and thus on the roller B. It often becomesnecessary to lift the rubbingroller up, so as to adjust the clothes whenthey become disarranged or caught in any way. This is accomplished bythe prop G, which is a kind of button hung to the face-plate F. Thisbutton, when the shaft I is lifted, is placed under it like a prop, andthus holds the roller B up from the lower rollers. The face-plate F isfor the purpose of preventing the upright D from splitting, and toprevent the shaft I from wearing the wood away, and also to act as aguide to the sliding journal-box J.

Having thus fully described the construction of our invention, we willshow the manner of attaching the same to the tub.- The devices for doingthis are shown in Figs. 4 and 5. They consist of the castings M and N.These are of difi'erent forms. The casting M consists of the back B andthe right-angle flange A on the lower side and a perpendicular tenon orlug, O. The casting N is formed of a back, 13, and two right-angleflanges, A"

A, one at the top and one at the bottom, with the lug 0 connecting thetwo. The casting N is much longer than the casting M. These are screwedto the sides of the tub, as seen in Fig. 1. The machine is attached tothe tub by these castings in the following manner: In each end of thebase-board H is sawed a narrow slot, 0, which admits the lug O. Themachine is put in the castings by first putting one end of thebase-board H into the casting N, and then shoving the other end downonto the casting M, the lug 0 always entering the slot (J.

The small rollers H H are not intended exclusively for the machineherein described. They can be used on any kind of a washingmachine wherea series of small rollers are used in conjunction with a largerubbing-roller.

What We claim as new is as follows:

1. The series of rollers H H, constructed and operated together asdescribed, in combination with the large rubbing-roller B, for thepurposes specified.

2. The button-prop G, in combination with the large rubbing-roller B,shaft I, and spring K, when arranged as and for the purposes set forth.

7 3. The rubbing-roller B, small rollers 11 H &c., uprights D D, andbase-board H, allarranged and constructed as described, in combinationwith the castings M and N, for the purposes described.
